Scientific Method...

This study stack is to help you prepare for a test on the scientific method.

What skills do scientists use? Scientists use the following skills: observing, inferring, predicting, classifying, and making models.
Define "observing". Observing means using one or more senses to gather information.
Define "quantitative". Quantitative observations deal with numbers or amounts.
Define "qualitative". Qualitative observations deal with descriptions that cannot be express in numbers.
Define "inferring". Inferring is making an inference based on reasoning from what one already knows.
Define "predicting". Predicting is making a "forecast" of what will happen in the future based on past experience or evidence.
Define "classifying". Classifying is the process of grouping together items that are alike in some way.
Define "making models". Making models involves creating representations of complex objects or processes.
What attitudes do scientists have? Scientists possess important attitudes, or habits of mind, including curiosity, honesty open-mindedness skepticism, and creativity.
What is "scientific inquiry"? Scientific inquiry is the diverse ways in which scientists study the natural world and propose explanations based on the evidence they gather.
How do you pose a scientific question? A scientific inquiry question should be able to be answered by making observations and gathering evidence.
Define "hypothesis". A hypothesis is a possible explanation for a set of observations or answer to a scientific question. It must be testable to be supported by evidence.
Define "variables". A variable is a factor that can change in an experiment.
Define "independent variable". An independent variable is the variable
Define "dependent variable". An dependent variable is the factor that may change in response to the independent variable.
Define "controlled experiment". A controlled experiment is an experiment where only one variable is changed at a time.
Define "operational definition". An operational definition is a statement tat describes how to measure a particular variable or define a particular item.
What type of data should one collect in an experiment? A scientist will collect both quantitative (numbers) and qualitative (descriptions) data when appropriate.
What attitudes to scientists have? Scientists possess important attitudes, or habits of mind, including curiosity, honesty, open-mindedness, skepticism, and creativity.
Define "conclusion". A conclusions is a summary, or analysis, of what you have learned from an experiment.
List the steps to scientific inquiry. The steps to scientific inquiry are: question, hypothesis, experiment, data, conclusion.
Define "scientific theory". A scientific theory is a well-tested explanation for a wide range of observations or experimental results.
Define "scientific law". A scientific law describes an observed pattern in nature without attempting to explain it.
What makes a picture a 2D model instead of just a picture? A model must include labels that help to explain a complex process or object.
When framing a scientific question, what do you have to make sure it includes? A well-developed question will give an experiment direction and let others know what you are trying to answer.
What is the proper format for a hypothesis in our class? In our class, we will use the "If___________________, then____________________." format. After the "if is the part the scientist will change (independent variable) and after the "then" is the result (dependent variable) of that change.
What information should a conclusion include for a scientific inquiry. A conclusion should include a summary of quantitative observations, whether the hypothesis was proved or disproved, an explanation of why, and any questions that arose, errors, and what future testing you might do for better understanding of the results.
List the 4 parts of a scientific inquiry. 1. Forming the Investigation 2. Designing the Investigation 3. Collecting and Presenting Data 4. Analyzing and Interpreting Results.
What needs to be included in the "forming the investigation" section? You should include the independent and dependent variables, how you will measure your variables, operational definitions, your question that you are investigating, a hypothesis, and background information in the "forming the investigation" section.
What needs to be included in the "designing the investigation" section? You should include your materials and procedure in the "designing the investigation" section.
What needs to be included in the "collecting and presenting data" section? You should include your qualitative and quantitative observations in the "collecting and presenting data" section.
What needs to be included in the "analyzing and interpreting results" section? You should include a summary of your quantitative observations, whether you proved or disproved your hypothesis, an explanation of the results, and a review of the design of the experiment in the "analyzing and interpreting results" section.
